Detailed Description

template<int dim, int spacedim = dim>
class FESystem< dim, spacedim >::InternalData

Usually: Fields of cell-independent data.

However, here, this class does not itself store the data but only pointers to InternalData objects for each of the base elements.

Definition at line 844 of file fe_system.h.

Constructor & Destructor Documentation

template<int dim, int spacedim = dim>

FESystem< dim, spacedim >::InternalData::InternalData	(	const unsigned int	n_base_elements,
		const bool	compute_hessians
	)

Constructor. Is called by the get_data function. Sets the size of the base_fe_datas vector to n_base_elements and initializes the compute_hessians field.

template<int dim, int spacedim = dim>

FESystem< dim, spacedim >::InternalData::~InternalData

(

)

Destructor. Deletes all InternalDatas whose pointers are stored by the base_fe_datas vector.

Member Function Documentation

template<int dim, int spacedim = dim>

void FESystem< dim, spacedim >::InternalData::set_fe_data	(	const unsigned int	base_no,
		typename FiniteElement< dim, spacedim >::InternalDataBase *
	)

Gives write-access to the pointer to a InternalData of the base_noth base element.

template<int dim, int spacedim = dim>

FiniteElement<dim,spacedim>::InternalDataBase& FESystem< dim, spacedim >::InternalData::get_fe_data

(

const unsigned int

base_no

)

const

Gives read-access to the pointer to a InternalData of the base_noth base element.

template<int dim, int spacedim = dim>

void FESystem< dim, spacedim >::InternalData::set_fe_values_data	(	const unsigned int	base_no,
		FEValuesData< dim, spacedim > *
	)

Gives write-access to the pointer to a FEValuesData for the base_noth base element.

template<int dim, int spacedim = dim>

FEValuesData<dim,spacedim>& FESystem< dim, spacedim >::InternalData::get_fe_values_data

(

const unsigned int

base_no

)

const

Gives read-access to the pointer to a FEValuesData for the base_noth base element.

template<int dim, int spacedim = dim>

void FESystem< dim, spacedim >::InternalData::delete_fe_values_data

(

const unsigned int

base_no

)

Deletes the FEValuesData the fe_datas[base_no] pointer is pointing to. Sets fe_datas[base_no] to zero.

This function is used to delete FEValuesData that are needed only on the first cell but not any more afterwards. This is the case for e.g. Lagrangian elements (see e.g. FE_Q classes).

template<int dim, int spacedim = dim>

virtual void FESystem< dim, spacedim >::InternalData::clear_first_cell ( )

virtual

Set the first_cell flag to false. Used by the FEValues class to indicate that we have already done the work on the first cell.

In addition to calling the respective function of the base class, this function also calls the functions of the sub-data objects.

Reimplemented from Mapping< int, int >::InternalDataBase.

Member Data Documentation

template<int dim, int spacedim = dim>

const bool FESystem< dim, spacedim >::InternalData::compute_hessians

Flag indicating whether second derivatives shall be computed.

Definition at line 864 of file fe_system.h.

template<int dim, int spacedim = dim>

std::vector<typename FiniteElement<dim,spacedim>::InternalDataBase *> FESystem< dim, spacedim >::InternalData::base_fe_datas

private

Pointers to InternalData objects for each of the base elements. They are accessed to by the set_ and get_fe_data functions.

The size of this vector is set to n_base_elements by the InternalData constructor. It is filled by the get_data function. Note that since the data for each instance of a base class is necessarily the same, we only need as many of these objects as there are base elements, irrespective of their multiplicity.

Definition at line 925 of file fe_system.h.

template<int dim, int spacedim = dim>

std::vector<FEValuesData<dim,spacedim> *> FESystem< dim, spacedim >::InternalData::base_fe_values_datas

private

Pointers to the FEValuesData objects that are given to the fill_fe_values function of the base elements. They are accessed to by the set_ and get_fe_values_data functions.

The size of this vector is set to n_base_elements by the InternalData constructor.
